I remember being horrified by this effect when I was watching Star Wars on my friend's TV. It looked like a high-school production. But he was so proud of his new TV that he didn't think it was weird at all.
A few years ago I was watching a movie at my parents' house during a visit over the holidays and I noticed something wasn't right. I kept saying the video motion was strange and apparently nobody else thought anything was strange. When we paused for a drink refresh I played with the settings and found the clear motion which I turned off. Problem solved. Nobody else thought it looked any different.
